• Remove the placing tool from the vice and empty the hydraulic oil from the rear of the tool. Remove the spare *Quick
Coupler – Male from the Quick Coupler - Female 11.
• Connect the spare *Quick Coupler - Female to the Quick Coupler - Male 10 on the Hydraulic Hose – Pull 19. This will
release any pressure from the pull side of the Piston 1 and ease the removal of the Piston.
• Screw the *Piston Bullet on to the front of the Piston 1.
• Place the Body 2 nose up on a bench. Then using a soft mallet, tap the Piston 1 towards the rear of the Body and out the
back end, taking care not to damage the bore within the Body.
• Note that when removing the Piston 1, oil on the pull side of the Piston will leak from the front and rear of the Body 2.
• When removing the Piston 1, the Front Seal Gland 16 may be retained on the Piston shaft. If this is the case, unscrew
the *Piston Bullet and pull the Front Seal Gland off of the Piston.
• The Piston Seal 32 is a 2-piece seal consisting of an external sealing ring and an inner O-ring. Using a small knife,
cut through the external sealing ring and remove from the external groove on the Piston 1. Then using a small fl at
screwdriver remove the inner O-ring from the Piston, and discard. When removing the seals, take care not to damage
the surface of the Piston.
• If the Front Seal Gland 16 is still retained in the Body 2. Place the Body nose up on a bench and then push the Front Seal
Gland from the front until it is free from the recess within Body. The Front Seal Gland can then be removed from the
back end of the Body. Take care not to damage the bore within the Body when doing so.
• Using a small fl at screwdriver remove O-Ring 29 and Spiral Back-up Ring 28, from the external groove on the Front Seal
Gland 16, and discard. When removing the seals, take care not to damage the surface of the Front Seal Gland with the
screwdriver.
• Remove Rod Seal 31 and Wiper Seal 27, from the internal grooves on the Front Seal Gland 16, and discard. When
removing the seals, take care not to damage the surface of the Front Seal Gland with the screwdriver.
• Remove the Front Bearing Ring 30 and check the part for wear or damage. Discard if necessary.
• Using a small fl at screwdriver, remove O-Ring 26 from the Body 2 and discard.
• Remove the spare *Quick Coupler - Female from the Quick Coupler – Male 10 on the Hydraulic Hose – Pull 19.
• Do not remove Set Screw 36 from the Body 2.
Assemble in reverse order to dismantling noting the following points:
• Clean all components before assembling.
• To aid assembly of seals apply a light coating of Molykote® 111 grease to all seals, seal grooves, back-up rings and the
assembly tools.
• Slide O-Ring 29 over the Front Seal Gland 16 and into the external groove. Insert the Spiral Back-up Ring 28 in the same
groove, in front of the installed O-Ring. Refer to the General Assembly and Parts List for the correct orientation of the
O-Ring and Spiral Back-up Ring.
• Press the Front Bearing Ring 30 into the internal recess within the Front Seal Gland 16 and then install Rod Seal 31
behind the Front Bearing Ring. Install the Wiper Seal 27 in the front recess of the Front Seal Gland. Refer to the General
Assembly to ensure the correct orientation of the Rod Seal and Wiper Seal.
• Lubricate the surface and leading edge of the Body 2 bore into which the Front Seal Gland 16 is to be installed with
Molykote® 111 grease.
• Lubricate the spigot on the *Front Gland Guide Rod tool and then place the Front Seal Gland 16, Rod Seal 31 end fi rst,
fully over spigot.
• Insert *Front Gland Guide Rod into the rear of the Body 2 and then push the Front Seal Gland fully into the bore within
the Body. Reasonable force is required to insert Front Seal Gland into the Body, so the use of a press or vice may be
necessary. Remove the *Front Gland Guide Rod while ensuring that the Front Seal Gland stays in place.
• Lubricate the seal groove and major external diameter of the Piston 1 with Molykote® 111 grease. Slide the inner o-ring
from Piston Seal 32 over the front of the major Piston diameter and into the seal groove.
• Screw the *Piston Bullet on to the Piston 1. Place the *Piston Seal Sleeve over the Piston shaft and then place the outer
sealing ring from Piston Seal 32 over the *Piston Seal Sleeve so that it rests on the tapered diameter. Lubricate the
surface of the *Piston Seal Sleeve with Molykote® 111 grease.
• Place the *Piston Seal Plunger over the Piston 1 shaft and the *Piston Seal Sleeve so that the open end of the *Piston
Seal Plunger rests on the outer sealing ring of Piston Seal 32. Using the *Piston Seal Plunger, push the outer sealing ring
